The cartridge-holder assembly (1) comprises a cup-shaped body (2) in which there are formed
-
- an upper receptacle (3) adapted to receive a cartridge or pod (C) containing a substance (S) for the preparation of the beverage, and
- a lower duct (7) in communication with said receptacle (3) and intended to convey the beverage towards an underlying collecting container.
In said duct (7) there is provided a control valve device (9-15) including
-
- a valve seat (11),
- an associated section-throttling member (12), and
- a control device (13-15) capable of causing a relative movement of the section-throttling member (12) with respect to the seat (11), between a first and a second working position, to correspondingly vary the cross section of said duct (7) and the rate of the flow of said beverage between a minimum and a maximum value, respectively.
Description
This application is a National Stage of International Application No. PCT/IB2009/053531 filed Aug. 11, 2009, claiming priority based on Italian Patent Application No. TO2008A000631 filed Aug. 12, 2008, the contents of all of which are incorporated herein by reference in their entirety.
The present invention relates to a cartridge-holder assembly able to be coupled to a head dispensing hot water and/or steam for the preparation of a beverage, particularly coffee.
More specifically the invention relates to a cartridge-holder assembly of the type comprising a cup-shaped body in which there are formed
-
- an upper receptacle adapted to receive a cartridge or pod containing a substance for the preparation of the beverage, and
- a lower duct in communication with said receptacle and intended to convey the beverage towards an underlying collecting container.
It is an object of the present invention to provide an improved cartridge-holder assembly adapted in particular to enabling the manner in which the beverage is brewed to be varied.
This and other objects are achieved according to the invention in the form of a cartridge-holder assembly of the type specified above, characterized in that in the abovementioned duct there is provided a control valve device including
-
- a valve seat,
- an associated section-throttling member, and
- control means capable of causing a relative movement of the section-throttling member with respect to said seat, between a first and a second working position, to correspondingly vary the cross section of said duct and the rate of the flow of said beverage between a minimum and a maximum value, respectively.
In a currently preferred embodiment the valve seat is fixed and the section-throttling member is movable, and the control means comprise a rotatable cam member acting on the section-throttling member.
In one illustrative embodiment the cam member is carried by a shaft which is mounted rotatably in the abovementioned body.
This body advantageously has a handle which extends along a direction forming an angle with respect to the axis of the abovementioned duct, and said handle is made to be rotatable with respect to the body about this direction, and the abovementioned shaft rotates with said handle.
The invention further relates to a cartridge for the preparation of a beverage, particularly coffee, for use in an assembly of the type defined above.
Other features and advantages of the invention will be found in the following detailed description, given purely by way of non-restrictive example with reference to the appended drawings, in which:
In FIG. 1 the numeral 1 is a general reference for a cartridge-holder assembly according to the present invention.
The cartridge-holder assembly 1 is intended to be coupled to a head dispensing hot water and/or steam for the preparation of a beverage, particularly coffee, of a type known per se and not illustrated.
In the illustrative embodiment shown in the drawings the cartridge-holder assembly 1 comprises an essentially cup-shaped body 2 made of metallic material. In this body there is formed an upwardly open upper receptacle 3 capable of receiving a cartridge or pod C containing a substance S for preparing the beverage. The substance S may be ground roast coffee, for example.
In the example of an embodiment illustrated, the receptacle 3 has an essentially frusto-conical shape, and its lower portion contains an adapter disc 4 provided with a plurality of passages 5. Advantageously, a filter 6 made for example of a metallic material is arranged on top of the adapter disc 4.
Underneath the receptacle 3, in the body 2, is a lower duct 7 that extends underneath the adapter disc 4 to a dispensing spout 8.
In the top portion of the duct 7, immediately underneath the adapter disc 4, is an annular member 9 through which a passage 10 is defined. At the lower end of this passage, the member 9 forms a downwardly directed annular valve seat 11.
The annular member 9 may be made for example of a silicone resin.
Mounted inside the duct 7, beneath the member 9, in such a way to be axially movable, is a section-throttling member 12 made for example of metallic material.
In the embodiment illustrated, the section-throttling member 12 is ogival in general shape and is provided underneath with a horizontal slot 13 (see also FIG. 2 ) in which there sits a cam member 14 mounted on a horizontal shaft 15.
The shaft 15 is mounted inside the body 2 so as to rotate about a horizontal axis, partly through a lateral projection 2 a of this body, to which a handle or knob 16 is rotatably connected.
One end of the shaft 15 extends into the handle or knob 16 and is coupled to the latter so that the two rotate together.
The arrangement described above is such that a rotation of the knob 16 causes a corresponding rotation of the shaft 15 and of the associated cam member 14, which in turn brings about a vertical translational movement of the member 12 either upwards or (with the help of gravity) downwards.
The arrangement is preferably such that the member 12 is movable between an extreme raised position and an extreme lowered position, in which it defines, relative to the valve seat 11 of the member 9, in a first case a minimum cross section and in a second case a maximum cross section for the passage of the beverage. Correspondingly, the two abovementioned extreme positions of the member 12 correspond to a minimum value and maximum value, respectively, of the rate of flow of the beverage.
When the throttling member 12 is in the position corresponding to the minimum cross section of passage, the beverage is brewed at a slower pace. This maximizes the effect of extraction of substances from the pod or cartridge C.
On the other hand, when the member 12 is in the position corresponding to the maximum cross section of passage for the beverage, the beverage is brewed at a faster pace, and less of the substance S contained in the pod or cartridge C is drawn out.
By this means it is possible, using a single cartridge-holder assembly, to obtain beverages of varying characteristics, such as a “ristretto” espresso coffee, or a “lungo” coffee such as the so-called “Americano” coffee.
In the embodiment illustrated, the cartridge C has a lateral annular wall 20 made of a plastic material, preferably biodegradable, such as polylactic acid (PLA).
The lateral wall 20 of the cartridge preferably has an essentially frusto-conical shape.
The cartridge C also has a lower wall or bottom 21 of filter paper, and an upper wall or cover 22, also conveniently made of filter paper.
The cartridge C described above is completely biodegradable.
Naturally, without departing from the principle of the invention, the embodiments and details of construction may be altered considerably from those described and illustrated purely by way of non-restrictive example, without thereby departing from the scope of the invention as defined in the attached claims.
